Jones appeared baffled when addressing the media on Thursday after he was flagged by the United States Anti-Doping Agency for a potential Anti-Doping Policy violation. He and his team vehemently denied that he had knowingly taken any substance in order to gain a performance-enhancing advantage, and immediately requested his B sample be tested.

USADA on Friday confirmed to MMAWeekly.com that Jones’ B sample was tested and upheld the initial findings, although it would not reveal the substance or substances found in the June 16 out-of-competition drug test.

“I can confirm that Mr. Jones’ B sample results have been reported by the laboratory, and that the results confirm the findings of the A sample,” said Ryan Madden, USADA Media Relations Specialist.

The initial finding forced Jones out of his UFC 200 main event rematch with Daniel Cormier, but he now faces graver consequences. Jones now faces sanctioning from USADA, which could amount to two years or more on the sidelines. He, of course, also has the right to appeal the findings.

If it can be proven that the test results stemmed from a tainted supplement or supplements, it’s possible that Jones’ suspension could be much less than two years. Tim Means and Yoel Romero each had his suspension reduced when tainted supplements were involved.
